Description

Technical Field

[0001] The utility model belongs to the technical field of machine tool fixing fixtures, and particularly relates to a quick fixing fixture for workpieces of a numerical control machine tool. Background Technique

[0002] The numerical control machine tool has well solved the problems of processing complex, precise, small-batch and multi-variety parts. It is a flexible and high-efficiency automated machine tool, representing the development direction of modern machine tool control technology. It is a typical mechatronic product. When the numerical control machine tool is processing, the parts will be fixed by a fixture to ensure the processing accuracy.

[0003] When the numerical control machine tool is processing, the traditional fixture often drives a baffle to move through a screw to clamp the part during clamping. This process takes a certain amount of time to clamp the part, resulting in waste of time, affecting the processing speed and thus reducing the production efficiency, and will also lead to an increase in production costs. To solve the above problems, there is an urgent need for a quick fixing fixture for workpieces of a numerical control machine tool to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to: in order to solve the problem that when the numerical control machine tool is processing, the traditional fixture often drives a baffle to move through a screw to clamp the part during clamping. This process takes a certain amount of time to clamp the part, resulting in waste of time, affecting the processing speed and thus reducing the production efficiency, and will also lead to an increase in production costs, and a quick fixing fixture for workpieces of a numerical control machine tool is proposed.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: a quick fixing fixture for workpieces of a numerical control machine tool, including a mounting seat, a side plate is fixedly connected to the top surface of the mounting seat, a support plate is fixedly connected to the top of the side plate, a clamping assembly is arranged on the top surface of the mounting seat, a fixing assembly is arranged on one side of the clamping assembly, and a toothed groove is arranged on one side of the side plate.

[0006] As a further description of the above technical scheme:

[0007] The clamping assembly includes a baffle, a first rack is fixedly connected to the bottom end of the baffle, and a gear is meshed and connected to one side of the first rack.

[0008] As a further description of the above technical scheme:

[0009] Both the baffle and the first rack are symmetrically provided with two through the gear. The first rack is slidably connected to the groove opened on the top surface of the mounting seat, and a spring is fixedly connected to one side of the baffle.

[0010] As a further description of the above technical solution:

[0011] The other end of the spring is fixedly connected to the mounting seat. The bottom end of the baffle is fixedly connected with a slider, and the slider is slidably connected thereto through a groove formed on the top surface of the mounting seat.

[0012] As a further description of the above technical solution:

[0013] The fixing component includes a support block. A sliding rod is slidably connected to the support block through a through hole formed therein, and a bidirectional threaded rod is threadedly connected to the sliding rod through a threaded hole formed therein.

[0014] As a further description of the above technical solution:

[0015] A turntable is fixedly connected to the outer wall of the bidirectional threaded rod. A second rack is fixedly connected to one end of the sliding rod, and the second rack meshes with the tooth-shaped groove.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are as follows:

[0017] 1. In the present utility model, by arranging a spring therein, when clamping a part, pulling the baffle to move so as to compress the spring and leaving a proper distance between the baffles, placing the part on the support plate, and releasing the baffle, the baffle is driven to move by the spring, thereby fixing the part through it. Through this design, rapid fixation of the part is achieved, thereby reducing the time spent on fixing the part, reducing the overall processing time, reducing the time cost during the processing, and improving the processing efficiency. At the same time, through the gear, when pulling one side of the baffle to move, the other side of the baffle can be driven to move, making the operation simple and further reducing the time spent on fixing the part.

[0018] 2. In the present utility model, by arranging a second rack therein, after fixing the part through the baffle, rotating the turntable drives the bidirectional threaded rod to rotate, thereby driving the second rack to move through the movement of the sliding rod and meshing it with the tooth-shaped groove provided on one side of the side plate for fixation. Through this design, fixation of the baffle is achieved, avoiding the situation that during the processing, due to insufficient elastic force of the spring, the baffle moves under force and loses the fixation of the part, thus maintaining the stability of the baffle and preventing the part from being processed failed due to the baffle moving under force and losing the fixation of the part. At the same time, when fixing, rotating the turntable only slightly is sufficient to drive the second rack to move for fixation. Description of the Drawings
